Acute Myeloblastic Leukemia in Paroxysmal Nocturnal Hemoglobinuria

Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired hematopoietic stem cell disorder in which the blood cells demonstrate aberrant interactions with serum complement. In part, this is due to the absence of the complement regulatory protein, decay accelerating factor (DAF). A small number of patients with PNH have gone on to develop acute nonlymphocytic leukemia, which is thought to arise f...

Indications for hematopoietic stem cell transplantation.

Transplantation of hematopoietic stem cells derived from bone marrow or peripheral blood has been used as a therapeutic procedure since the mid-seventies. In recent years, the number of transplants reported annually to the European Group for Blood and Marrow Transplantation (EBMT) Registry is approximately 23,500 including 38% of allogeneic and 62% of autologous procedures. In most developed co...

Paroxysmal nocturnal hemoglobinuria with acute leukemia.

T HE OCCURENCE of impaired marrow function in paroxysmal nocturnal hemoglobinuria (PNH) has long been recognized. A smaller group of patients, with an initial diagnosis of aplastic anemia, have been noted to develop signs of PNH during the course of their illness.1 Such persons have been said to have “the aplastic anemia-paroxysmal nocturnal hemoglobinuria syndrome.”2 Also evident, in some case...
